PIC12F675T-I/SN

Microcontrollers Overview

The PIC12F675T-I/SN is an 8-bit CMOS microcontroller from the PIC12F series, manufactured by Microchip Technology. It features a high-performance RISC CPU with 35 instructions and operates at frequencies up to 20 MHz. The device includes 1024 words (1.75 KB) of Flash program memory, 64 bytes of SRAM, and 128 bytes of Data EEPROM. Key peripherals include a 10-bit Analog-to-Digital Converter with four channels, an analog comparator module, Timer0, and Enhanced Timer1. It utilizes an 8-pin SOIC package.

Microcontrollers Feature Summary

• Integrates a precision internal 4 MHz oscillator factory calibrated to ±1% alongside external crystal support.
• Features high endurance non-volatile memory with 100,000 write cycles for Flash and 1,000,000 write cycles for EEPROM.
• Includes a 10-bit ADC module with programmable voltage reference inputs and multiple channel selection options.
• Supports low-power operation with Sleep mode and independent Watchdog Timer oscillator for reliable system monitoring.

Microcontrollers Applications

• Industrial control systems requiring robust code protection and interrupt capabilities.
• Battery-powered portable devices utilizing wide operating voltage ranges and low standby currents.
• Sensor interface circuits leveraging the integrated analog comparator and ADC modules.
• Embedded applications needing direct LED drive capability through high current sink/source pins.

Microcontrollers Procurement Notes

Verify the specific suffix 'T' indicates tape and reel packaging when sourcing this component. Confirm the '-I' designation aligns with industrial temperature range requirements for your application environment. Ensure compatibility with standard In-Circuit Serial Programming protocols via the GP0 and GP1 pins during integration.

Microcontrollers Selection Notes

Select this model over the PIC12F629 variant if analog signal processing is required, as it uniquely includes the 10-bit A/D converter. Consider the SOIC-8 surface mount package for automated assembly processes compared to through-hole alternatives. Evaluate the 20 MHz maximum clock speed against power consumption constraints, noting that lower speeds significantly reduce active current draw.

Microcontrollers Part Context

This component belongs to the PIC12F629/675 family of 8-pin flash-based microcontrollers. It shares the same core architecture and instruction set as the PIC12F629 but adds analog functionality. The T/I/SN suffix combination specifies the industrial temperature grade, SOIC-8 package, and tape-and-reel shipping format.
